Better Magic Mouse software.

[onehandle]

A couple of weeks ago I linked to a hack that gives the Magic Mouse a single extra function.

Forget that. This is the real thing. And it's free.

MagicPrefs is a free menubar application for OSX which aims to improve the functionality and configuration options of the Apple Magic Mouse.
It features the ability to bind a variable number of finger clicks, taps, swipes, pinch and other gestures to functions like Middle Click , Hold Down Both Mouse Buttons , Spaces , Expose, Dashboard etc.
Touch Sensitivity implements a single point control for a number of factors impacting the algorithms of the taps, swipes, pinch and other gestures.
Tracking Speed adds the ability to increase the maximum mouse speed by a extra 200%.
Also featured is a real-time display of the fingers touching the surface of the mouse that you can enable to test and monitor the way the mouse sees your input.

1. Just a caution

I installed this and it worked like it said, but it conflicted with my computer and I had to remove it. I actually got the grey screen of death and could not see my hard drive. I used tech tool to take every vestige of it off and did a full unplug etc. and my baby is up and running again. The only thing I added was this app. So....be careful. FYI: 27inch early 2009 imac with snow leopard installed. Magic mouse, wireless keyboard.
